Application filed January 11, 1900. Serial No. 1,036. (No model.)

To all whom it may concern: the walls of the socket somewhat back from Be it known that 1, JAMES H. FLEMING, a the mouth. The ball in turn rests on and citizen of the United States, residing at Newis supported by the oppositely-beveled periphark, in the county of Essex and State of New eries of two disks d d, lying in parallel planes 55 Jersey, have invented certain new and useful and adapted to turn oppositely on the same Improvements in End Bearings for Rotary axial center.

At each side of the two disks are heavy tubular shaft-sections Z Z, axially coincident with said disks. The ends of the shaft-sections next to the disks are recessed, as at m, to form races for the balls 17..

Said sections are screwed inwardly toward each other until the proper adjustment of the ball-bearings is secured and are then held in position by lock-nuts h, arranged on said sections. The adjacent faces of the disks cl are grooved, as at q, to receive balls which form a bearing between the two disks.

From the foregoing description the operation of the device is apparent. As the shaft ct rotates the ball 0 turns upon a vertical axis, causing the two disks to revolve in opposite directions. The various bearings offer very little frictional resistance, and the shaft turns easily and with little loss of power.

Having thus described the invention, what I claim as new is- 1. The combination with the rotary shaft and ball 0, of a pair of oppositely-movable disks supporting said ball, and supports for said oppositely-movable disks, substantially as set forth.

2. The combination with the rotary shaft, disks cl, d, adapted to rotate in opposite directions, and having balls interposed therebetween and plates f, f, arranged outside of said disks and balls interposed between said disks and plates, substantially as set forth.

3. The combination with a rotary shaft, of i a pair of beveled disks for supporting said shaft, balls holding said disks in parallel planes, balls arranged between said disks to hold the same apart, and supports providing raceways for the first said balls, the said disks being beveled and together forming a groove, substantially as set forth.

4.. The combination with the shaft having bearing-wheels i, 71, for holding the ball in the groove formed by said beveled disks and means for holding said disks in operative position substantially as set forth.

5. The combination with a rotary shaft, and a ball, 0, of disks d, cl, balls 19,19, and p and plates f, all arranged and adapted to operate, substantially as set fort-h.

6. The combination with the rotary shaft Ct, anda ball a, supporting the same, of disks beveled at their peripheries to receive the ball 0, and having raceways on opposite sides, platesf, also having raceways, and balls disposed between the disks and between the disks and plates, substantially as set forth.

7. The combination with the rotary shaft or, of disks, each beveled at its periphery and provided with raceways on opposite sides, balls interposed between the disks, plates disposed near the outer sides of said disks and having raceways, balls interposed between the plates and disks, a shaft 6, supporting said plates and means for adjusting said plates on said shaft, substantially as set forth.

8. The combination with the rotary shaft to, of disks movable in opposite directions and provided with raceways on opposite sides, ballsinterposed between the disks, plates disposed near the opposite outer sides of the disks and having raceways, and one of said plates being threaded, balls interposed between the plates and disks, a shaft extending through said plates and disks, said shaft having a shoulder g, and threads to receive the threaded plate, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 9th day of September, 1899.

JAMES H. FLEMING.
